Application filed. July 20, 1914.

T all whom it may concern Be it known that I, EUGENE DAUCHER, a

citizen of the United States, and a resident of the city of New York, Yoodside, borough of Queens, in the county of Queens and State of New York, have invented a new and improved Automatic Firelxtinguisher, of which the following is a fuil, clear, and eX- act description.

My invention consists of an automatic fire extinguisher and the object in View is to simplify and improve devices of this character in such a manner as to cheapen tiieir structure, facilitate their operation by causing them to operate without extremely excessive heat and to sprinkle the Water for the extinguishing of the tire over a large area.

A. further object of the invention is comprehended in the provision of an automatic tire extinguisher in which the working parts are mounted upon a supply pipe and which includes a rotatable nozzle normally held closed by a readily combustible element composed of a series of cloth or fibrous strands which can be economically renewed to norinally hold the nozzle closed, while spring means are provided for normally tending to move the nozzle to an open position upon it being released by the destruction or burning of the thre ds or fibrous strands.

A still i rther object of the invention is comprehended in the provision of sprinkling means attachable over thenozzle in such a. manner that the form thereof may vary, while the operating parts are inclosed in a complete combustible bag or closure to which a fuse may be attached for hastening the opening of the nozzle of the eXtin guisher.

With the above and other objects in view, the invention resides in the peculiar combination and arrangement of `parts to be hereinafter more fully described, illustrated and claimed, it being also an object yto provide a device which is simple in construction, durable and elicient in operation and not likely to get out of Working order.

Reference is to be had to the accompanying drawings forming a part of this spe-cication, in which similar characters of reference indicate corresponding partsy in all the views, and in which* Figure 1 is a side elevation of an automatic fire extinguisher constructed in ac- Specieation of Letters Patent.

cordance with my inveption, one type of sprinkler being shown and the bag or inclosure being omitted; Fig. 2 is a longitudi nal sectional view taken on the line 2-2 of Fig. 1; Fig. 3 is a cross sectional View taken on the line 8 3 of F ig., 1; Fig.. 4 is a cross sectional View taken on the line 4-11 of Fig. 1; Fig. 5 is a side elevation of the complete automatic fire extinguisher; and Fig. 6 is a sectional view illustrating the application of another form of sprinkling device to the improved extinguisher.

As illustrated in the drawings, the numeral 10 designates a supply pipe for water, steam or other extinguishing fluid from the mains or other reservoirs under pressure, t0

the sprinkler end of which a nozzle is pro vided'consisting of a cap 11 which is threaded to the supply pipe as shown at 12 by interior threads on its Hnge 18 and exterior threads on a reduced portion ot the discharge end of the supply pipe so that the exterior surface of the cap and pipe will lie substantially flush. The cap .is provided with a pair of spaced segmental or sectorshaped openings 14 located at diametrically opposite points of its center, and an enlarged perforated sprinkling nozzle proper 15 having a flanged portion 16 engaged on exterior threads o'f the iange 13 of the cap is mounted over the latter to spread the water throughout a large area. rlhis nozzle proper has an end or intermediate wall 17 which is provided with a pair of spaced segmental or sector-shaped openings 18 so located as to be normally disposed at right angles relative to the openings 11i, to close the end of' the supply pipe. The nozzle provided with the openings 18 yand loosely threaded on the cap may be used with or without the perforated enlargement if desired, the water or extinguishing fluid in either instance passing `through the openings after the nozzle is rotated on the cap.

For the latter purpose, the supply pipe 10 is provided with an enlargement or shoulder 19 spaced from its discharge end, and a longitudinally extending arm 2O is xed to said enlargement so as to remain stationary with the pipe. A ring or sleeve 21 is rotatahly mounted on the supply pipe between the enlargement 19 and the rin 21 and at its ends is connected to or engage with the stationary enlargement and the rotatable ring tending to normally rotate the ring and the nozzle therewith in such a manner as to dispose the openings 14 and 18 in alinement.

In order to hold said openings out of alinement and thus close the end of the supply pipe a depending wing 24 is fixed to the ring 21 and between the wing and they stationary arm a plurality of combustible threads or fibrous strands 25 are passed, the same preferably extending through an eye 1o 26 carried by the arm. The spring tends to' normally rotate the ring and nozzle in an anti-clockwise direction, but by reason of the threads connected as specified, pull is exerted on the threads against the stationary arm 15 20 so as to hold the ring and nozzle against rotation while the openings 14 and 18 are out lof alinement and the discharge end of the supply pipe is closed against the outlet of water or extinguishing lluid. In this 20 manner, when the threads areignited or destroyed by the presence of lire or otherwise, although the same are advantageous by reason of their extreme readiness of combus-l tion, the spring will act to rotate the ring on the threads 16 and the movable part of nozzle therewith and by engagement of the arm 2O with a longitudinally extending stop member 27 also fixed to the shoulder 19 and projecting therefrom diametrically opposite 30 to the arm 20, the sleeve will be permitted to turn 90 before the attaching part 28 of the wing 24 engagesthe stop member 27, while the openings 14 and 18 will be disposed in. alinement so as to permit the escape of Water. Normally, the threads or fibrous strands are under tension, as shown in Figs. 1 and 3 of the drawings, when they are disposed to connect the Wing at the base of a `frame which is of triangular form and the arm fixed to the shoulder, and when in this position the spring is contracted, as shown in Fig. 1, but when the threads are burned the spring expands to rotate the ring and nozzle and the nozzle remains open to cause the water or extinguishing fluid to be sprayed or sprinkled over a large area to extinguish any blaze or obviate further destruction.

In order to further insure destruction of 50 the threads or fibrous strands 25 and the opening of the nozzle to allow the discharge of the extinguishing fluid, the parts enumer-` ated, with the exception of the perforated l, nozzle proper, are covered with a,readily '50 combustible inclosure or bag 29 which fits over the supply pipe and around the same beyond the enlargement 19 and in rear of the perforated nozzle, While a fuse 30 is con-1 nected tothe apex of the frame together with the bag or inclosure, thus presenting a larger surface to the heat or flame to result in the burning of the threads. In lieu of the perforated nozzle 15 a structure much similar to an ordinarylawn sprinkler'is employed. the same comprising an attaching part 31 having a rotatable part 82 With branch pipes 33 having sprinkling nozzles 34 at their ends, all facing in opposite directions to' rotate and spread'the Water or extinguishing fluid over a larger area and to act in the manner of a lawn sprinkler.

By a device constructed in accordance with this invention it Will be unnecessary to use a composition material which' requires excessive heat in order to'result in the open- 75 ing of the sprinkling nozzles, as in the present instance the threads or fabric including the inclosure or bag are readily combustible as distinguished from the usual materialy which simply fuses or melts. It will also be 30 obvious that steam or any fire extinguishing fluid may be used in lieu of Water and that the device is especially adapted to be placed on the Walls or ceilings of Steamers Where there is inflammable or combustible material stored or Where crossed Yelectric wires are situated, and to be arranged in accordance with the advice of any architect, builder or designer of a steamer or Whatever building the devices are applied to, such as theaters, factories, stables or the like. The device is very small and compact and by reason .of its simple construction can be economically produced and will occupy a minimum of space when in use. y
